fMRI at 1.5, 3 and 7 T: characterising BOLD signal changes

Blood oxygenation level dependent (BOLD) signal changes occurring during execution of a simple motor task were measured at field strengths of 1.5, 3 and 7 T using multi-slice, single-shot, gradient echo EPI at a resolution of 1x1x3 mm(3), to quantify the b ...

On the origin of the MR image phase contrast: An in vivo MR microscopy study of the rat brain at 14.1 T

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Rajika Maddage

Recent studies at high magnetic fields using the phase of gradient-echo MR images have shown the ability to unveil cortical substructure in the human brain. To investigate the contrast mechanisms in phase imaging, this study extends, for the first time, ph ...

T2 Relaxometry of Human Median Nerve

Giulio Gambarota

This article examines the T2 relaxation characteristics of the median nerve. Knowledge of the T2 relaxation time is essential to optimize clinical magnetic resonance imaging (MRI) protocols and to enhance the visibility of pathophysiological changes in tis ...

Snapshot gradient-recalled echo-planar images of rat brains at long echo time at 9.4 T

Rolf Gruetter, Hongxia Lei, Nathalie Just

With improved B-0 homogeneity along with satisfactory gradient performance at high magnetic fields, snapshot gradient-recalled echo-planar imaging (GRE-EPI) would perform at long echo times (TEs) oil the order of T-2*, which intrinsically allows obtaining ...

In vivo H-1 NMR measurement of glycine in rat brain at 9.4 T at short echo time

Rolf Gruetter, Lijing Xin, Giulio Gambarota, Chiara Perazzolo

Glycine is an amino acid present in mammalian brain, where it acts as an inhibitory and excitatory neurotransmitter. The two detectable protons of glycine give rise to a singlet at 3.55 ppm that overlaps with the more intense myo-inositol resonances, and i ...

Magnetic resonance imaging and T2 relaxometry of human median nerve at 7 Tesla

Giulio Gambarota

Measurements of T2 relaxation times in tissues have provided a unique, noninvasive method to investigate the microenvironment of water molecules in vivo. As more clinical imaging is performed at higher field strengths, tissue relaxation times need to be re ...
